Discussion

Net-SNMP TCP Disconnect Remote Denial Of Service Vulnerability

Net-SNMP is prone to a remote denial-of-service vulnerability. The issue is exposed when Net-SNMP is configured to communicate over TCP; Net-SNMP using UDP is unaffected.

This issue affects Net-SNMP when running in 'master agentx' mode. An attacker can exploit this issue to cause the affected service to crash, effectively denying service to legitimate users.
